## Review summary

Overall, MM Ruler is praised for accurate, quick measurements and real ruler functionality, with many users finding it useful and reliable. However, the experience is dominated by intrusive ads, unskippable banners, and reports of adware behavior. The monetization (high weekly subscription) is widely criticized as excessive or a scam. Some users also note a limited measuring range and compatibility issues with certain phone cases. Addressing ads and pricing would greatly improve usability.

### Pros

- Useful for quick, small measurements
- Provides everything needed in a measuring tool
- Reliable and generally works as advertised
- Positive overall impression as an excellent/fantastic app

### Cons

- Intrusive ads and pop-ups that hinder usability
- Adware-like behavior: installs extra apps without permission
- Expensive subscription model / no acceptable free usage
- Limited measuring range / cannot measure long objects
- Compatibility issues with some phone cases rendering the ruler unusable
